United States Patent | 5,123,524 |
Lapeyre | * June 23, 1992 |
A conveyor belt composed of a plurality of interconnected modules, each of identical construction and end to end mateable. Each module includes a multiplicity of elongated parallel spaced link elements terminating in first and second link ends. An intermediate section between the link ends is of grid-like structure providing a box beam across the width of the module for structural strength. This intermediate section also includes angled surfaces which define sprocket recesses located midway between the pivot axes and which are adapted to mate with corresponding sprocket teeth of an associated sprocket wheel. These intermediate sprocket recesses provide the benefit of minimizing chordal action and scrubbing between the mating surfaces of the module and sprocket.
